Last night someone asked me if you have higher torque numbers on a chassis dyno or and engine dyno. I said you would get more from a chassis dyno because of gear reduction and thus torque multiplication. I know they say you lose about 20% horsepower on a chassis dyno. Anyone know for sure or have numbers from both?

 

I gotta see this. All I can say is it's surprising that you can get higher torque numbers out of my 6th (.73) than with my 5th (1.00), but that might also be more load = more time for turbo to spool.
